Hi!
----
The follwoing example code...
-- snip --
namespace xmlfragmentparser
{
typeset -T parser_t=(
typeset -a data # "raw" data from .sh.match
compound -a context # parsed tag data
function build_context
{
typeset dummy
typeset attrdata # data after "<tag" ...
integer i
for (( i = 0 ; i < ${#_.data[@]} ; i++ )) ; do
nameref currc=_.context[$i] # current context
dummy="${_.data[i]/~(El)<([:_[:alnum:]-]+)(.*)>/X}"
currc.tagname="${.sh.match[1]}"
attrdata="${.sh.match[2]}"
if [[ "${attrdata}" != ~(Elr)[[:space:]]* ]] ; then
dummy="${attrdata//~(Ex-p)(?:
[[:space:]]+
( # four different types of
name=value syntax
(?:([:_[:alnum:]-]+)=([^\"\'[:space:]]+?))| #x='foo=bar huz=123'
(?:([:_[:alnum:]-]+)=\"([^\"]*?)\")| #x='foo="ba=r o" huz=123'
(?:([:_[:alnum:]-]+)=\'([^\']*?)\')| #x="foox huz=123"
(?:([:_[:alnum:]-]+))
#x="foox huz=123"
)
)/D}"
integer j k
compound -a currc.attrs
nameref attrs=currc.attrs
for ((j=0 ; j < ${#.sh.match[0][@]} ; j++ )) ;
do
# FIXME: Replace "! -z" with "-v" once
-v works on .sh.match
if [[ ! -z "${.sh.match[2][j]}" && ! -z
"${.sh.match[3][j]}" ]] ; then
attrs+=(
name="${.sh.match[2][j]}" value="${.sh.match[3][j]}" )
elif [[ ! -z "${.sh.match[4][j]}" && !
-z "${.sh.match[5][j]}" ]] ; then
attrs+=(
name="${.sh.match[4][j]}" value="${.sh.match[5][j]}" )
elif [[ ! -z "${.sh.match[6][j]}" && !
-z "${.sh.match[7][j]}" ]] ; then
attrs+=(
name="${.sh.match[6][j]}" value="${.sh.match[7][j]}" )
fi
done
print -u2 -v attrs
#print -u2 -v .sh.match
fi
done
}
)
}
# main
set -o nounset
.xmlfragmentparser.parser_t xd # xml document
xd.data=( "<foo x='1' y='2' />" "<bar a='1' b='2' />" )
xd.build_context
print "$xd"
-- snip --
... should AFAIK print something like this...
-- snip --
(
typeset -a data=(
$'<foo x=\'1\' y=\'2\' />'
$'<bar a=\'1\' b=\'2\' />'
)
typeset -a context=(
[0]=(
typeset -a attrs=(
[0]=(
name=x
value=1
)
[1]=(
name=y
value=2
)
)
tagname=foo
)
[1]=(
typeset -a attrs=(
[0]=(
name=a
value=1
)
[1]=(
name=b
value=2
)
)
tagname=bar
)
)
)
)
-- snip --
... but instead ast-ksh.2012-07-27 gives me lots of weired error
messages like "x.sh[58]: xd.build_context[44]: print: xd: is not an
element of xd" and doesn't have a 2nd array element in the "attrs"
arrays ([1]).
AFAIK the main trouble is caused by the line with "nameref
attrs=currc.attrs" (which causes that currc.attrs remains empty) and
the namespace (which triggers the " xd: is not an element of xd"
warning...)...
[1]=this is likely the previously reported issue with ${#.sh.match[0][@]}
